Another Rube Goldberg machine

I already talked about a Rube GoldBerg machine before.
Machines that do a very simple task in a very complex way.
While they are known and conceived to be useless, I can totally understand the appeal of building them and seeing them in action.

How does the egg become a chicken? How does the balloon pieces become pieces of paper?
Let me know in the comments.
